Abstract (en)
[origin: WO2016102266A1] The invention relates to a mains-coupled inverter (2) for feeding current into an energy supply network (5), having an output bridge arrangement (230) which is driven via a pulse width modulator (241), wherein a periodic auxiliary signal is used to determine switching times of the output bridge arrangement (230), the frequency of which auxiliary signal varies according to a predefined periodic wobble signal (Umod), and having a synchronization unit (243) for phase synchronisation of the auxiliary signal with the energy supply network (5), wherein the synchronization unit (243) is configured to set a predefined phase offset (ΔΦ0) of the periodic auxiliary signal in relation to a phase of the energy supply network (5). The inverter (2) is characterized in that an additional synchronization unit (245) is present which is configured for phase synchronization of the periodic wobble signal (Umod) with the energy supply network (5). The synchronization unit (243) and the additional synchronization unit (245) each comprise a phase-locked loop circuit, and the periodic wobble signal (Umod) is passed via a correction signal generator (216) and an adder (203) for oscillation suppression on a control section of the phase-locked loop circuit of the synchronization unit (243). The invention also relates to an arrangement having at least two inverters (2) of this type, and to a method for operating an inverter arrangement of this type.
